Astilbe durable and easy-care group perennial. Astilbe is a genus of 18 species of rhizomatous flowering plants within the family Saxifragaceae, native to mountain ravines and woodlands in Asia and North America.
These hardy herbaceous perennials are cultivated by gardeners for their large, handsome, often fern-like foliage and dense, feathery plumes of flowers. They are widely adapted to shade and water-logged conditions, hence they are particularly associated with pond-side planting. They also tolerate clay soils well. Numerous hybrid cultivars have been raised. Flowers of at least some Astilbe species have a strong and pleasant aroma.
